1 To all whom it may concern:

consists in'certain procedures which-willbe' hereinafter fully describedand pointedout- .In the'accompanying drawings Figure is a plan view of atank witha numberof ticalsection. a

A represents an outer tank, and l, 1 are a number of sheet metal'canstherein The tank is insulated as is customary,'and a cover 2 is adaptedto be placed over it, as shown in 1 Fig. '2. In the centerof each can aipe 3 is located for diseharg'ing'air the'reinto for This pipe 3 isconnected by the exible coupinto the can orfcansa A- branch pipe '2exfor agitati' the brine contained therein, and this -ai .discharge'pipehas a valve 11. he main- 5 is provided with valves 2 and 13.

The cold anunoniagasis conducts through the tanks in coils 14 whichextend-beneath the. bottoms and adjacent to the sides. and

ends of the cans andjventsout through the discharge pi e 15.. IA valvein the inlet" pip'e'17 of this cold ammonia gascoil'l lconti'ols thepassage of cold ammonia gas there-T through. A p1 e18-supp1ies hotammonia to the pipe 1-7 hu the, igh-pressure line, and 'afvalve 19controls"this'su'pply.

I rthe operation of the process the valves 12 1-3 and 16 are-opened-andthe valves 9,-1-1

. and mareclosed. Thisopens-the-main-to the air pump, and the cold amnoniagas pipe toits supply, sothat air is bei v, forced into .the' waterin the'cans while the essprogresses. When the ice has been oi' md canstherein, and Fig. 2 is a longitudinal verprogresses,

' zi' procin the cans and only a cup of impurities remains at thecenter, the valve 13 iscloserl shutting off the air pressure, andvalvetl is opened and in this way the water in the cup is sucked outthrough the pipe 3 by means of the suction pump and discharged into thesevver, or. otherwise disposed of. New, to thaw the ice loose from thecans the pipe 3 is removed, valves 9, 12 and 16 are closedgg nd valves19, 11 and 13 are opened. Valve 19 allows hot ammonia to flow throughthe coils 14, and this heats the brinein which the cans are submerged Bythe o ening of valves 11 and 13 air is .pumpe into the brine throughpipe 10, and the Whole body of brine is agitated, thus greatlyaccelerating the heating of the latter, so ha the method of harvestingthe ice is greatly hastened and facilitate r I a From the foregoing itwill be observed that the whole process of manufacturing and harvestingthe ice is greatly facilitated, andvthe time required ,for thecompletion of the process materially reduced. 1 f

More or. less sli" ht changes might be resorted tofiin the, processwithout departing from the spirit and scope of my invention, and. henceI do notwish to limit myself to the exact method herein described, buthng 4 to amain 5., and an anipum 6 is provided for forcing air throughsai i main, out

. Iiiavin fully "described my invention,

what E c aim as new-and desire to secure by Letters Patent, isi

;-1.. Theprocess of'manufacturin and har- 2 vesting; ice which consistsin inc osing the ,water to befrozenin an oblong container,

"a plurality of jetsfapproximatelyl along the longitudinalcentrsil planeof the can whereby the inside faces of the plates of ice formed ontheside walls' of the container are substantially straight and parallel,and subse- (fluently removing ,the unfrozen water from between'theplates of ice formed.

2. .Theherein described process of manufacturing and harvestin'g ice,which consists in conveying a freezing medium in pipes,-

passing -througha freezing liquid in which. fthemans are submerged, andsubsequently conveying. a thawifig substance throughsaid pipes andagitating .the freezing liquid whereby to facilitate the uniformheating'of thelatter 1 3. The herein-deecri. process of manu-Tact-lining 'ice which consists in submerging applying wheezing mediumto the exterior surfaces ofsaid container, discharging air in thawingthe ice from the receptacle.

The herein-described method of manufacturing ice which consistsinsubmerging in a can exposed on all surfaces a measured or predeterminedquantity of Water to be frozen, in a liquid medium, conducting arefrigerating mednun through said hquid perature of the medium and causethe, freez- 5 ing; of the measured quantity of Water in the can, andsubsequently Withdrawing the 1 refr'zerating medium from'the pipes andsaw formly whereby to thaw the ice loose on all ituting a thawing mediumand passing it through said pipes, whereby to heat the l E medium inpipes whereby to reduce the tem- I l l l l '1 entire vohune ofsubmerglng medium unisurfaces of the can in which it has bcen formed.

S., "lhe herein-described method of manufacturing ice which consists insubmerging aimeasured quantity of Water to be frozen in a liquid mediumwhereby said water to be frozen is exposed on all surfaces to theinfluences of the submerging liquid, then conducting a refrigerantthrough said medium whereby to cause it to freeze the measured quantityof water, and finally Withdrawing the refrigerant and introducing athawing medium in its place whereby to raise the temperature of thesubmerging liquid to cause it to thaw the ice from the cans.

In testimony whereof I afiix my signature 7 in presence of twowitnesses.
